Description

Technical Field

[0001] This utility model relates to the field of model aircraft technology, specifically a linkage structure for a twin-tail model aircraft. Background Technology

[0002] Model aircraft, as the name suggests, are model airplanes built to resemble actual aircraft. They are non-manned aircraft designed for recreational use. Model aircraft have transcended the narrow scope of research for aerospace scientists, becoming a learning and recreational tool for aerospace and aviation enthusiasts. In model aircraft, steering during flight is controlled by rotating the vertical stabilizer, while steering during taxiing is controlled by rotating the tailwheel. Typically, servos are installed on the fuselage to control the vertical stabilizer and tailwheel rotation, respectively.

[0003] The existing announcement number CN217745716U discloses a linkage structure for model aircraft, used to control the left and right swinging of the vertical tail and tail wheel, including a vertical tail swing arm, a drive assembly, a vertical tail connector, and a tail wheel assembly. The vertical tail swing arm is rotatably connected to the fuselage. The drive assembly is mounted on the fuselage, and its output end is connected to the vertical tail swing arm to drive the vertical tail swing arm to rotate. The vertical tail connector is connected to both the vertical tail swing arm and the vertical tail, and is used to drive the rear-driven vertical tail to swing left and right by the vertical tail swing arm. The tail wheel assembly is connected to both the vertical tail swing arm and the tail wheel, and is used to drive the rear-driven tail wheel to swing left and right by the vertical tail swing arm. The drive assembly drives the vertical tail swing arm to rotate, and the rotation of the vertical tail swing arm drives the vertical tail to swing through the vertical tail connector, and drives the tail wheel to swing through the tail wheel assembly; the swinging of the vertical tail and tail wheel is controlled simultaneously by a single drive assembly.

[0004] While existing technologies have achieved linkage of the vertical tails, they cannot achieve control of the twin vertical tails and cannot be linked simultaneously with the front wheel. Therefore, we propose a linkage structure for a model aircraft with twin vertical tails. Utility Model Content

A first vertical tail control surface bracket is installed on the first linkage wire, and a second vertical tail control surface bracket is installed on the second linkage wire.

[0007] The lead screw servo drives the first carbon rod and the rear connecting wire to reciprocate. The rear connecting wire is connected to the vertical tail rocker arm. An intermediate connecting piece is installed in the middle of the third carbon rod. The intermediate connecting piece is connected to the vertical tail rocker arm through the second carbon rod.

[0008] The front wheel is equipped with a front wheel spoke, the front wheel spoke is equipped with a front wheel axle, the front wheel axle is equipped with a front wheel rocker arm, and the front wheel rocker arm is connected to the first carbon rod via a front connecting wire.

[0009] Preferably, a front wheel axle sleeve is fitted on the outer side of the front wheel axle, and the front wheel rocker arm and the front wheel axle are fixed together by front screws.

[0010] Preferably, it also includes a fixing base, on which the tail rocker arm is fitted, and a rear screw for limiting the position of the tail rocker arm is installed on the top of the fixing base.

[0011] Preferably, the vertical tail rocker arm has an L-shaped structure.

[0012] Preferably, the first vertical tail rudder surface bracket is equipped with a first vertical tail, and the second vertical tail rudder surface bracket is equipped with a second vertical tail.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by driving the twin vertical tails through the lead screw servo motor, the rear connecting steel wire, the vertical tail rocker arm, the intermediate connecting part, the third carbon rod, the connecting part, the linkage steel wire, and the vertical tail control surface bracket, the twin vertical tails are moved. At the same time, the nose wheel rocker arm is driven by the steel wire through the mounting hole on the vertical tail rocker arm, so that the nose wheel moves together with the twin vertical tails, achieving the effect of aircraft linkage. The structure of this application is simple and can achieve the effect of simultaneous linkage of the twin vertical tails and the nose wheel. Attached Figure Description
